United Airlines has made significant strides in 2026 to ensure that the vast majority of its fleet is equipped with charging options. On almost all international long-haul aircraft (767, 777, 787), you will find universal AC power outlets and USB ports at every seat in all cabins. For domestic flights, United is currently rolling out its "United Next" interior; as of 2026, over 200 narrow-body planes (737 MAX, A321neo) feature AC outlets and USB-C ports at every seat, even in Economy. Furthermore, the new 2026 domestic First Class seats include wireless charging pads built into the armrests. It is worth noting that some older "United Express" regional jets and older 737-700s may still lack in-seat power, so it is a "best practice" to check the "Amenities" section of your specific flight in the United app 24 hours before departure to see what is available at your row.
